Installing the Finderscope

To install the finderscope onto the telescope you must first mount the finderscope through the finder bracket and then attach it to the telescope. Toward the rear of the telescope tube, near the focusing assembly, there is a small bracket with a set screw in it. This is where the finderscope bracket will be mounted. To install the finderscope:

1.Slide the rubber O-ring over the eyepiece end of the finderscope and roll it 2/3 of the way up the finderscope.

2.Insert the eyepiece end of the finderscope through the bracket until the O-ring presses tightly between the finder and the inside of the bracket.

3.Tighten the adjustment screws until they make contact with the finderscope body.

4.Locate the mounting bracket near the front (open) end of the telescope.

5.Loosen the set screw on the mounting bracket on the telescope.

6.Slide the finder bracket (attached to the finderscope) into the mounting bracket on the telescope.

7.The finderscope bracket will slide in from the back. The finderscope should be oriented so that the objective lens is toward the front (open) end of the telescope.

8.Tighten the set screw on the mounting bracket to hold the finderscope in place.

For information on aligning your finderscope, see Telescope Basics section of this manual.

Installing the Eyepieces

The eyepiece, or ocular as it is also called, is an optical element that magnifies the image focused by the telescope. Without the eyepiece it would be impossible to use the telescope visually. The eyepiece fits directly into the focuser. To attach an ocular:

1.Loosen the set screw on the eyepiece adapter so that it does not obstruct the inner diameter of the barrel.

2.Slide the chrome portion of the eyepiece into the focuser.

3.Tighten the set screw to hold the eyepiece in place.

To remove the eyepiece, loosen the set screw on the focuser and slide the eyepiece out. You can replace it with another ocular.
